[Q] What's the difference between CDMA and GSM ROM builds? - Galaxy Tab Q&A, Help & Troubleshooting

Hey everyone,
I'm searching for a ROM for my VZW galaxy tab and I'm finding a heck of a lot of ROMs for GSM devices. My tab is not in service any longer (which means that I don't exactly need the CDMA part). Does this mean that I can safely install a GSM ROM that doesn't come with a modem built in (like Overcome v2.0.0RC1)? Or are there more subtle differences that prevent me from doing that?
UPDATE: Okay, so while looking around, I found out that you can theoretically do it by flashing a ROM and then a kernel specifically for a CDMA device. Is this correct, and if so, would I be safe by first installing Overcome v2.0.0RC1 and then Voodoo Plus v5?

Thats not totally accurate ...
The kernel still has to be coded to work with that rom.
Kernel is between the software and hardware and tells the hardware how to react with the software... And vise versa...
So just flashing a cdma kernel followed by a gsm rom most likely won't work without some serious tweeking.

So those of us with a CDMA tab (Verizon and Sprint) we cannot upgrade our tabs? Great... Will there be a release for the CDMA tabs? Hope so...

Thanks for the info. That clarifies things. Wow, I'm regretting my decision to go with Verizon right now. Anyway, I'm sure that when Samsung said that they're going to update the tabs, they included Sprint and Verizon customers.

Yes, the italian update was apparently early... So don't expect it immediately, but a samsung release woulda include both versions.

Root Canadian 3G Nexus One

I am curious I have the Rogers Wireless version of the Nexus One in the mail.
I can't get a definitive answer on if cyanogenmod will work on it without a problem?
I sure hope this isn't like the Rogers version of the G1.
Thanks,
Not at all like the Rogers Dream. The AT&T/Rogers version (I have read), is identical to the Tmo, except offers Rogers/AT&T 3G Band, 850mhz.
Procedure is the same as written elsewhere. You can skip the step for upgrading radio, I believe the newer N1's shipped with the newest radio. I don't have the instructions, followed the CM wiki. Just remember to skip the radio update part of the instructions. I believe the radio update allows root on stock ROM. When you upgrade to CM ROM for example, it is already rooted, which is why you can bypass this step.

Yes, you can install CM and it will work without any problems... essentially, the devices are the same, except for the radio... which is why there is a new RIL library and firmware module...
CM 5.0.5+, Enom 1.7.1, MCR 1.9+, ModacoDesire A16+ are all compatible with the new N1 and have the latest RIL & Firmware module...
And yeah, the new N1 has the latest radio image, so you don't have to update/faslh the radio...

No!!! DON'T DO IT!!! You're phone will be bricked!
J/K... this question has been asked a dozen times and a search would have yielded an answer in 10 seconds for you.

I wonder how radically different the Canadian N1 is to the US N1!
The only risk/problem you will expose yourself with tinkering is if you mess up with flashing the radio firmware. I used the latest cyanogen, recovery, and bootloader all while retaining the original radio firmware. (why fix it if it aint broken?)

Would the 2.42.02.10.29 Sprint CDMA Hero Radio update work on non-Sprint networks?

Hi all!
I have a CDMA Hero, that can run and is running Sprint branded ROMs with no issues. My service is through a regional carrier called Carolina West Wireless to make it clear, not Sprint. I've run several Sprint branded ROMs and currently have AOSP 2.3.2 without any issues with roaming or anything like that.
My question just is would the 2.42.02.10.29 radio update, as posted by theimpaler747, work for me? Reading through the threads I can't see where this has come up so I hope I'm not repeating a question.
Thanks!
I already upgraded this version radio, looks like no side effect and impact. But I don't know what improvement or bug fix for new version. BTW, I'm from China, using Carrier China Telecom.
AS long as you stick with a cdma hero radio, you can flash it fine. At one point, people here were even flashing a verizon radio from the eris, and it worked fine
Thanks for the responses, I flashed the new radio, no problem!

Rogers Captivate the same as At&t Captivate?

Any one know if there the same? hardware wise? Like if I where to flash a US/at&t
based rom would it run/work on a Rogers Captivate?
Its my understanding that some of the at&t roms work with the Rogers version...But do all of them work?

From what I understand, they will work, but there are caveats, though they can be fixed some way or another.

Well like I said, I'm just assuming, but here is a Rogers ROM that you may be interested in: http://forum.xda-developers.com/showthread.php?t=914284
But I know that they will work. You can try flashing one and seeing for yourself what issues arise.
Ironically, there is little if any Rogers left in that rom.
I have an i896(rogers), and so far everything is good. I have yet to flash a rom, but the kernals work as well as the modems.
On the sticker inside the battery cover, the only thing that says i896 is the model number. Every other designation on the sticker refers to the phone as an I897
my build number is 1011.
Guys, the rogers captivate is literally the exact same, other than the model number. Every rom I've tried has worked without a glitch, and I've been flashing for a few months now.
Thank you for your input Escapist! You answered my question!

[Q] Milestone with US ATT Custom ROM

I have been looking for an answer to this and if it has been answered before, point me to the thread.
I'm using a Telus Milestone here in the US with ATT. I have GOT OR 2.01 loaded on my milestone and it's rooted in everything. Now the next step would be to pick a firmware for 2.2.1. However, There is nothing listed for ATT or US at all for that matter.
Should I use Telus's Firmware? And will it still work with ATT? I want to load some custom roms, but I'm a bit stuck. Thanks for any input.
You should use Telus firmware. Or any firmware you like, but flash Telus baseband on top in order to get it working on AT&T
Check in milestone Android development thread, there are few choices available (roms), pick one. There is still no official Froyo rom for Milestone though. Most of the custom roms available are nearly fully functional.

Thank you very much. I wanted to try it, but I didn't want to guess, be wrong, and be screwed. Thats all I needed!

Couple debranding questions

I've currently got a working gold card for my ATT HD7S. I'm able to flash any ROM (including the 5.x Europe ROM).
First question: other than the ATT ROM, which STOCK ROM would be most appropriate for a T9295?
Second: This will sound paranoid, but I'm concerned about the different modem/radio. In terms of interference, I don't want to do anything dangerous or illegal. Could flashing a European T9292 ROM to my T9295 create any issues in this regard? Maybe enable bad WiFi frequencies, broadcasts, etc.?

Why are you wanting to flash a different stock rom? What would be the advantages?
I've flashed the DFT rom to my HD7S and not had any issues.

I'm actually considering flashing the T-Mobile ROM. Reports over at Microsoft Answers suggest that the T-Mobile update has fixed the Zune Music freeze problem. It's driving me nuts, and I'm never expecting a fix for the HD7S...
Based on the speaker/call quality issue, it's pretty obvious that they don't care about major functions being broken on this phone.

Also, DFT is based on the generic Europe ROM, right?
Still wondering about this. Are region specific settings like Wifi channels dependent on the ROM or the device? Will an American device with a European ROM use Wifi on channels 12-14 (against FCC rules)? Surely not? I'm only asking because I read somewhere that using channel 12 might have been causing WiFi ICS issues.
